ATAFD still reusing freed memory in latest snapshot

Last week, Nate Lawson reported a panic in 5.1-CURRENT as described
below. However, despite the apparent resolution, doing a clean install
on an IBM t40 with the most recent snapshot from
snapshots.jp.freebsd.org still results in the same panic for me.

I can provide more information as necessary.

Thanks,
